Assignment of d.h.w. heating

•
Assignment of d.h.w. heating to the respective consumers
•
All relevant time switch programs are taken into consideration
•
Controllers in holiday mode are taken into consideration
Determines the consumers for which d.h.w. will be heated and which time switch
programs will be appropriately considered, also checking whether the relevant
controllers are in holiday mode.
1. Press the operating line selection buttons to select operating line 123.
2. Press the + / – buttons to select the required assignment.
Setting range
0...2
Depending on the selection made, the d.h.w. will be heated for the following
consumers:
0 For the local consumer only (RVA47.320)
1 For all consumers (controllers) in the same segment
2 For all consumers (controllers) in the LPB system
In the case of d.h.w. heating according to the heating circuit time switch program
(operating line 121, setting 1), the time switch programs are used from the appropriate
range for the release of d.h.w. heating at the nominal temperature setpoint, based on
the consumers selected here.
With all settings (operating line 121, setting 0 - 2), it is checked whether the controllers
of the selected range are in holiday mode. Controllers in holiday mode will not be
considered for d.h.w. heating.
If all controllers in the selected range are in holiday mode, d.h.w. heating will not be
released. Only the frost protection function will remain active (function with no setting).

Number of d.h.w. charging cycles

•
Choice of one or several d.h.w. charging cycles
•
Forward shift of release matched to the number of d.h.w. charging cycles
With this setting, d.h.w. heating can be reduced to one charging cycle per day. The
forward shift of d.h.w. heating against the range selected on operating line 123 will be
appropriately adjusted.
This setting is effective only if, on operating line 121, setting 1 (according to the heating
circuit time switch program(s)) has been selected.
1. Press the operating line selection buttons to select operating line 124.
2. Press the + / - buttons to select the type of d.h.w. heating.
